To all whom it may convent: v

- Be it known that I, ALVIN L. HART, a resi- Moines and State of certain new anduseful forating-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable which it appertain's to make and use the same. p q My invention relates to improvements in erforating .machines, and more articu- Iowa, have invented music rolls, the object to provide im roved mechanism therefor, which insure accurate punohi'n of the sheet in-accordance with a master s set or with a piano or similar instrument, and the invention consists in certain novel features of construction and combinations and arrange- 'ments of parts as will be I after-described and pointed out in the claims.

. with cutters secure In the accompanying, drawings, Figure 1 isa diagrammatic view illustrating my improvements controlled by a pianola. Fig. 2 illustrates a piano or similar key controlling mechanism. I Fig. 3 is an end or face view showing the cutter mechanism and Fig. 4 is a view of the gearing. I

-/ 1 represents: a-frame having parallel cross bars 2 and 3, and 4 re resents cutter holders therein. The cutter bars are mounted in elongated slots in lower bar 3, with the cutters 5 projecting up through slots in bar 2, and each cutter holder 4 is provided with a spring 6 which serves the twofold-function of maintaining the holders out I of the path of a double cam roll 7,and the hold the cutter holders an cutters against the rear ends of the slots in thebar2.

'The springs as above explained, not only cutters in inoperative position but also maintain-the cutters is first forced us a airist the rear ends of the slots in bar 2. T lie purpose of this is that when the cutter through the paper,-it will be carried forwar by the pa er and will not I tear the same, as would be t e case if the cutsate for the moving of the tershad no forward movement to compenaper.

Supported in frame 1, a ove bar 2 a roll 8 is located, this roll being preferably of hard steel and made withannular' grooves to receive the cutters and the grooves are but in the county of Des Improvements in Per:

mechanism for pe crating. of the invention being punchesand controlling piece played upon a 'orrarms 19, at the ends more fully hereinical driving roller 37. 37, a pulley37 ley, motion'is transmittedto a pulley 37 on-' the journal of master-sheet slightly wider than the cutters latter a shear cut therein.

1 9 represents a reel or spool, from which 'a strip to be perforated, is drawn over aguide roller 10, beneath and in close contact with roll 8, thence overa perforated air blast tube 11, and thence under a live roller 12, against which the paper is frictionally held by a roller 13. Above 4 tube 11, a rotary cutter 14 is supported in the frame. This cutter comprises a series of elongated blades which have a shearing action with 15, adjustably clamped bars 16. a

A cross-bar 17 is secured above roll 8, and has a seriesof bowed sprin fingers 18 projecting into the grooves of rofi 8, to reventthe cut strips or tongues winding on t e roll, and

of bar 17, an oil saturated wick 19 is su ported and is locatedin the path of the blad keep the latter oiled, so that with the shearw ing action of-the blades of the rotary cutter to give the between supporting against the cutter bar, the blades will be kept sharp.

To each and every cutter holder, cords 20 are secured, passed over pulleys 21 and secured to ang e bars or bell-cranks 22, and these bell-cranks are erated by the bellows 26 of a pianola or other instrument, each bellows being connected by a tube 23 with its proper opening in the tracker, board 24 over 25 is passed from roll to roll.

On the end of the shaft carrying paper live .roll 12, a truncated conicalroller connecta similar truncated con- On a journal of roller is secured, and from this puled by abelt 36 with of a belt 2 5. Parallel with the rollers 35 and a 37 is a screw 38 on which a-flanged pulley 39 is located and turned byv the belt 36 and as the pulley is turned and feed the belt from end to end of the trun'- cated conical rollersto gradually decrease the relative to its increasing speed ofmaster roll 39 is also secured tothe s1ze. A. large gear shaft of roll 12 and on a'st'ub 41 projecting from the frame of the machine. A pulley" 42 is also mounted on the stub .41 to rotate with the a belt 43 passes over this 44 on the. shaft of cam roll a fixed cutter bar 7'5 es of rotary cutter 14 to connected with and opj.

It will be borne in mind that as the mastersheet is rolled up on the roller on to which it 1 1s transferred in performing thepiece of music, it willgradually increase its speed in would not be played in the same time. means of these truncated rollers 35 and 37 passing through the machine as the paper winds upon the roller and if the piece of paper being slotted passed through the cutter ata uniform rate ofspeed this would vary the distance apart of the slots so that the piece the pulley being set at the extreme left at the beginning of the passage of the master-sheet through the machine, as the paper winds upon the roller the pulley passes to the'right and so decreases the speed with which the beginning of the cutting will be exactly 9 over guide master-sheet passes throu h the machine that the final. result is that a l the slots in the new roll are out at "exactly a uniform rate, so that a slot representing an eighth note at the the same length as a slot representing an eighth note at the conclusion of the piece. If it were not for these truncated rollers, then the slot at the conclusion would be shorter than the slot at the beginning, although they represented the same notes. I

' The operation of my im rovements, above described, is as follows material to be erforated, is drawn off spool ro ler 10,under roll 8, over perforated blast tube 11, and between rollers 12 and 13. The rotary cutter 14 and cam roller 7 are -continuously rotated at high speed, the gearing being illustratedin Fig- 4. When an opening in the master-sheet exposes an opening in the tracker board 24, the bellows 26 connected with said opening will move its bell-crank 2 2, and pull its cord 20, which will draw the cutter i'lOld6T'4 forward into the path of cam roller 7 and the latter will force the cutter 5 up through the paper, and the cutter will be r'eciprocated to cut as long as it is held in position to be moved by the cam roller. When passes over the opening in the tracker-boar 24, the bellows 26 move the cutter holder out of the path of cam roller 7 and draw the cutter It. will thus be-seen that the cutter wi form a-slot-in the paper in exact accordance with the o ening inthe master-sheet as the cutter will e reci rocated by the cam roller just'as long as t e cutter holders are thereby. As the paper passes over tube 11, the air issuing from the perforations therein, will blow the tongues cut out bythe cutters, up into the path ofrotary cutter 14, which latter will cut.

oif the tongues against bar 15 leaving a smo'o th rectangular openingin the paper.

he paper 'or other the master-sheet 'openin will move the bell-crank 22' back to normal position, and spring 6 will.

out of the When the keys of a piano or other like instrument are .to be employed, a structure similar to that shown in Fig. 3 is used, and which will now be explained.

27 represents, the key of a piano or similar instrument, provided with a headed )in 28 of copper or other material, located between metal contact strips 29 but normally out of contact therewith. I v 30 re resents a frame to be tightly clamped on trac er-board 24 and ispro'vided with a se ries of openings alining with the o ienings in the board, each of said openings icing normally closed by a valve 31 controllcdby an electro1nagnet 32, in electric circuit with a battery 33 and contact strips 29. It will thus be seen that when a keyis depressed, the head of its in 28will contact with stri )S 29 and close til i suit in the magnet 32 immediately opening valve Bland compel the cu ttcrs to operate as above explained, it being understood that there is an electro-magnet for-each key of the instrument and when any key is operated its magnet will open the proper valve to compel the proper cutter to act and tho cutterwill perforate the paper just as long and no longer than the key 18 epressed, for the circuit will be broken and the valve ately the key is released.

Agreat many changesmight be madein the 31 will close immcd igeneral form and arrangement of the parts described Without departing from my invention, and hence, I do not restrict myself to the precise details set forth but consider myself at liberty to make such slight ehangcs and alterations as fairly fall within the spirit and scope of my invention. i
